2023-07-18ASoC: Intel: sst: Convert to PCI device IDs definesAmadeusz Sławiński1-4/+10
Use PCI device IDs from pci_ids.h header. BSW replaces CHV, as 0x22a8 was added in PCI header as BSW ID for consistency, as they are same (similar) platforms. The ACPI IDs are used only internally and lower 16 bits uniquely define the device as vendor ID for Intel is 8086 for all of them. Use PCI_DEVICE_DATA() to match PCI device to be consistent with other Intel audio drivers.

2022-08-15ASoC: Intel: sst: Replace sprintf() with sysfs_emit()Takashi Iwai1-4/+4
For sysfs outputs, it's safer to use a new helper, sysfs_emit(), instead of the raw sprintf() & co. This patch replaces those usages straightforwardly with a new helper, sysfs_emit().

2022-04-05ASoC: intel: atom: Remove superfluous flush_scheduled_work()Takashi Iwai1-1/+0
It seems that flush_scheduled_work() is called without any real purpose at sst_context_cleanup() (the driver doesn't put works on the global queue at all). As the flush_schedule_work() function is going to be abolished in near future, let's drop it now.

2018-03-01ASoC: Intel: sst: Free streams on suspend, re-alloc on resumeHans de Goede1-1/+23
The Bay Trail SST-DSP firmware version looses track of all streams over a suspend/resume, failing any attempts to resume and/or free streams, with a SST_ERR_INVALID_STREAM_ID error. This commit adds support for free-ing the streams on suspend and re-allocating them on resume, fixing suspend/resume issues on devices using this firmware version. This new behavior gets triggered by a new flag in sst_platform_info which only gets set on Bay Trail platforms. This has been tested on the following devices: -Asus T100TA, Bay Trail + ALC5642 codec -Ployer MOMO7W, Bay Trail CR + ALC5652 codec Tested-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-06-16ASoC: intel: Use kvzalloc() for suspend buffersTakashi Iwai1-11/+11
Intel SST driver allocates lots of pages at suspend for saving the firmware states, and this may occasionally lead to the allocation error due to the high order, ending up with the suspend failure. Use kvzalloc() so that it can fall back to vmalloc() gracefully. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-06-06ASoC: Intel: sst: Delete sst_shim_regs64; saved regs are never usedDouglas Anderson1-19/+0
In commit 9a075265c6dc ("ASoC: Intel: sst: Remove unused function sst_restore_shim64()"), we deleted the sst_restore_shim64() since it was never used. ...but a quick look at the code shows that we should also be able to remove the sst_save_shim64() function and the structure members we were storing data in. Once we delete sst_save_shim64() there are no longer any users of the 'sst_shim_regs64' structure. That means we can delete it completely and also avoid allocating memory for it. This saves a whopping 136 bytes of devm allocated memory. We also get the nice benefit of avoiding an error path in the init code. Note that the saving code that we're removing (and the comments talking about how important it is to do the save) has been around since commit 336cfbb05edf ("ASoC: Intel: mrfld- add ACPI module").
